Product Description

High performance spiral classifier for mineral processing

How it works: The classifier which form closed-circuit work with grinding mill in the factory need the machine which can lift grit, so this kind of classifier called mechanical classifier, actually the classifying process conduct still depending on the different sedimentation rate of the particle. Mechanical classifier sometimes wash the ore which contain the clay or desliming and dewatering for the ore except pre-classification and classification check as the auxiliary equipment of grinding. The spiral classifier is simple structure, easy operation, big inclination of classify tank, so that it can be connected with the grinding mill by gravity flow easily, that is why it is widespread in application. Other kinds of classifiers in our country are still in use, but has stopped manufacturing. The shape of spiral classifier is a rectangular tank, the tank inclination is 12°to 18.5°, and the bottom of tank seems a semicircle. In the tank equipped with 1 or 2 long axis, and along the axis, continuously installed with spiral blade. The drive mechanism drives the spiral axis start rotation. Slurry is fed from the side of tank, it become settlement classified layer at the bottom. Coarse particles sink to the bottom and then spiral blade transport it to the discharge at the top, at same time it will be dewatered during this transportation, unsettled fine particles carried by slurry flow and discharges from the overflow weir. Classifying process is basically same with the desliming cone, on the classifier tank there is a lifting mechanism which can adjust the distance of blade and bottom , and the axis can be lifted up when close down to avoid that settled sand bury the blade.
